[0002] Generator bearing oil mist absorption generally adopts an external oil suction motor and stainless steel pipeline. The oil suction motor and oil collection box are designed outside the wind tunnel. When oil mist is generated inside the thrust oil tank, the motor absorbs the oil mist into the external oil collection box. For large generator sets, the pipeline from the thrust oil tank to the outside of the generator (outside the wind tunnel) is long. Generally, a section of pipeline connected by steel pipe is set in the middle of the pipeline to reduce the damage to the pipeline interface caused by vibration during equipment operation and pipeline use. The two ends of the steel hose are fixed with pipe clamps, but because the pipeline surface is not absolutely smooth, the pipe clamp cannot fix the steel hose and the pipeline tightly, and oil leakage will occur at the end when the motor absorbs oil mist; on the other hand, the power of the oil mist motor is fixed and cannot be adjusted according to the amount of oil mist, and there may be over-absorption.
